How does it work?
The Internet is a global network of computers linked via telephone cables
and optic fibres. Some of these computers are constantly connected to the
Internet while others just drop in for a visit. Every computer permanently
connected to the net stores (or hosts) a bunch of information which can be
accessed by other net users.
To get to that information, you need to link your computer to another one
which is already "online" or a part of the Internet. You can link two
computers together with a cable, which is common in an office, or through
a telephone line, which is what happens when you connect to an Internet
Service Provider from home. While you are connected to that other computer,
you become one of the millions of computers that make up the Internet.
What's an Internet Service Provider?
An Internet Service Provider is a company with a fast computer which is
permanently connected to the Internet through a 'big pipe' (fast connection).
This company then
sells you the right to connect to its computer and use a part of its pipeline
to the rest of the world. Once you have an Internet connection you can access
any of the information on any one of the million computers connected to the
net. You can also provide your own information for other people to access.
To get your computer to talk to your ISP's computer, you need a modem,
which helps to translate your computer's digital signals into the telephone
line's analogue signals, and you need software which will help your computer
speak to other computers. You can buy a modem from any good computer store.
Try and get one of the latest models for better speed and support. Some of
the software you need may have come with your computer. Other pieces of
software should be given to you by your ISP. Still others you can download
(transfer to your computer) once you are connected.
Is that all?
In the next couple of pages, we explain how to find an ISP,
how to use the Web, how to send e-mail,
and how to transfer files across the Internet. These
are the three main activities which people do on the Internet to start with.
You can also read news groups, play computer games, chat online, have a
video conference or use a phone to talk to people around the world.
You can find all of the essential Internet programs you need for your
computer right here on this CD-ROM.
